Fix crash closing File Browser window after closing temporary render window

This seems to be a longer standing issue. Steps to reproduce were:
* With factory settings, Ctrl+O then F12
* Close the render window using the window close button
* Close the File Browser window using the window close button

This could be OS specific though, at least on macOS this caused a crash.
